Abstract

Summary: By oxidative coupling polymerization of the macromonomer of oligoaniline and p‐phenylenediamine, we have prepared an electroactive copolymer, exhibiting an exciting molecular structure, and interesting spectroscopic and electrochemical properties. The polymerization characteristics and structure of the copolymer were systematically studied by gel permeation chromatography (GPC), Fourier‐transform infrared (FTIR) spectroscopy, ^1^H NMR spectroscopy and X‐ray powder diffraction (XRD). UV‐vis spectra were used to monitor the chemical oxidation process of the reduced copolymer. The electrochemical activity of the copolymer was tested in 1.0 M H~2~SO~4~ aqueous solution. Three redox peaks were shown, which is different to that for polyaniline. The thermal properties of the copolymer were also evaluated, by thermogravimetric analysis (TGA); the electrical conductivity is about 5.53 × 10^−5^ Scm^−1^ at room temperature, upon a preliminarily, proton‐doped experiment.
